Super-resolution data assimilation
Sébastien Barthélémy, Julien Brajard, Laurent Bertino +1
Increasing the resolution of a model can improve the performance of a data assimilation system: first because model field are in better agreement with high resolution observations,…
Probabilistic forecasts of sea ice trajectories in the Arctic: impact of uncertainties in surface wind and ice cohesion
Sukun Cheng, Ali Aydoğdu, Pierre Rampal +2
We study the response of the Lagrangian sea ice model neXtSIM to the uncertainty in the sea surface wind and sea ice cohesion. The ice mechanics in neXtSIM is based on a brittle-li…
Data Assimilation in the Geosciences - An overview on methods, issues and perspectives
Alberto Carrassi, Marc Bocquet, Laurent Bertino +1
We commonly refer to state-estimation theory in geosciences as data assimilation. This term encompasses the entire sequence of operations that, starting from the observations of a…
Towards the inclusion of wave-ice interactions in large-scale models for the Marginal Ice Zone
Timothy Williams, Luke Bennetts, Dany Dumont +2
A wave-ice interaction model for the marginal ice zone (MIZ) is reported, which involves both the attenuation of ocean surface waves by sea ice and the concomitant breaking of the…
